6 Dangers of of artificial sweeteners


1. They over stimulate our taste buds.

In some cases, artificial sweeteners can be up to 600-3,000 times sweeter than natural sugar. Scientists suggest that after a consistent intake of artificial sweeteners, our taste buds become less receptive to the sweetness of normal sugar. Because of the intense stimulation of artificial sweeteners, our taste buds begin to grow dull and cause us to seek out more and more artificial sweeteners to satisfy our sweet tooth.

2. They trick your gut.

Susan Swithers, PhD, professor of behavioral neuroscience at Purdue University and a leading researcher on artificial sweeteners, says that your gut gets confused when you eat zero-calorie-but-super-sweet artificial sweeteners. The sweet taste sends a signal to your gut that something high calorie is on its way, so your gut anticipates foods that do, in fact, have a high calorie count. But when those don’t arrive, your gut doesn’t utilize the foods efficiently, and that causes a cascading effect that interferes with your body’s hunger signals.

3. They throw off your hormones.

Part of that cascading effect has to do with the hormone insulin. When you taste sweet foods, even if they have zero calories, your body still releases insulin as if you’d eaten sugar. Insulin leads to blood sugar spikes, which increase cravings. Swithers’ research has also suggested that artificial sweeteners prevent your body from producing GLP-1, a hormone that controls blood sugar levels and feelings of satiety. Combined, the two haywire hormones could be causing you to feel hungrier and eat more.

4. They make you overeat.

It’s not just a biochemical reaction that leads artificial sweeteners to pack on the pounds. Natasha Turner, ND, author of The Super-Charged Hormone Diet, says that artificially sweetened foods could trick you into overeating because of they way they feel in your mouth. “The taste and feel of food in our mouth influences our learned ability to match our caloric intake with our caloric need,” she says. High fat, high sugar foods taste both sweet and dense, signaling to your brain that they’re high calories. But artificially sweetened foods often have a thinner consistency and texture than sugar-sweetened foods and thus, aren’t as satisfying. “Our natural ability to control how much we eat and, therefore, our body weight may be weakened when this natural link is impaired by consuming products that contain artificial sweeteners,” she says.

5. They increase the risk of diabetes.

The two above, combined, could explain why a number of studies have found that diet soda drinkers are at an increased risk of developing type 2 diabetes. Researchers aren’t clear as to why they’re seeing this relationship, whether it’s the fact that people eat other unhealthy foods that undo any calorie-saving effects of a no-calorie drink or if it’s something biological related to the drinks’ artificial sugars. But something is obviously amiss: A recent study from the University of Texas found that people who drank diet soda were 65 percent more likely to be overweight than people who drank no soda and, more bizarre, they were more likely to be overweight than people who drank regular soda.

6. They’re polluting your water.

Artificial sweeteners are meant to be hearty—they’re designed to withstand the harsh conditions of your body so they won’t break down and add calories. Because they’re so potent, they don’t break down in the environment, when exposed to light, oxygen and microbes, either. In a 2009 study published in the journal Environmental Science & Technology, Swedish researchers detected sucralose and acesulfame K in treated wastewater, including samples that were pulled from a municipal water-supply source. They also noted that the artificial sweeteners hadn’t degraded in wastewater sludge after a period of seven hours. Canadian researchers got the same results four years later; sucralose and acesulfame were found in each sample drawn from a river that collects wastewater from 33 different treatment plants.
